Dr Evalle is Board Certified and specializes in Internal and Geriatric medicine but not alzheimers or dementia. There are specialists that deal directly with these issues just as if you came to him with a heart condition he would send you to a heart doctor. He runs a private practice and has no partners. He is not "Cherry Picking" what he wants to do, he is doing what he does best.
Its always frustrating trying to find new medical professionals at any age.. it is only made more difficult when we are dealing with a specific illness that requires specialized care and we personaly are not familiar with all the isssues or types of care available.
If you read Wikipedia, there are many types of subspecialities of geriatric medicine..to include alzheimers and dementia.
